A high silica ratio means that more calcium silies are present in the clinker and less aluminate and ferrite. SR is typically between 2.0 and 3.0. Alumina Ratio (AR) The alumina ratio is defined as: AR=(Al 2 O 3 /(Fe 2 O 3) This determines the potential relative
Calcium Silie Hydrate - an overview | ScienceDirect Topics
Calcium Silies Hydrates (CSH) is the major hydration product of Portland Cement. It has been intensively studied for several decades. CSH can be obtained by hydration of C3 S and β-C 2S or by precipitation from aqueous solutions containing a Ca salt and silie ions. CSH has a wide range of chemical composition.

Strength development in concrete - Understanding Cement
Measurement of concrete strength. Traditionally, this is done by preparing concrete cubes or prisms, then curing them for specified times. Common curing times are 2, 7, 28 and 90 days. The curing temperature is typically 20 degrees Centigrade. After reaching the required age for testing, the cubes/prisms are crushed in a large press.
